Bugs Fixed

Row counts in TokuDB could be lost intermittently after restarts. Bug fixed #2.

In TokuDB, two races in the fractal tree lock manager could significantly affect transactional throughput for some applications that used a small number of concurrent transactions. These races manifested as transactions unnecessarily waiting for an available lock. Bug fixed #3.

TokuDB could assert when opening a dictionary with no useful information to error log. Bug fixed #23.

TokuDB could assert for various reasons deserializing nodes with no useful error output. Bug fixed #24.

Percona Server could crash when running a query over a partitioned table that uses an index to read a range of rows if this range was not covered by any existing partition. Bug fixed #1657941 (upstream #76418).

With two client connections to a server (debug server build), the server could crash after one of the clients set the global option userstat and flushed the client statistics (FLUSHCLIENT_STATISTICS) and then both clients were closed. Bug fixed #1661488.
